I have a Duron 750 that I did not connect the bridges on. Am I right in assuming that if I put a Duron 750 in this is will run at 1000 since it is locked at 7.5x? I don't have a pen to connect the bridges, so I want to try this first - if it doesn't run at 1 Gig, I could buy a pen and try a lower multiplier.
